Twilight Sparkle has become the new princess of Equestria . . . but she might be the last as well. An old enemy of the nation demanded control over the sun and moon more than a thousand years ago, but Celestia refused. War broke out and Equestria almost lost. Now that Twilight is the ruler, they will either gain control . . . or a second war will be born. As the Elements of Harmony defend their home however, there is more behind their demands than they thought.
